I do the same as Jeff.   But I have a major issue with recognizing cell phone numbers (except for my husband's 😉)

Unfortunately, cell phone area codes can be from all OVER the country, even if the client is local.   And the ability to 'spoof' any number, with a local area code, is rampant.

I actually kept an excel spread sheet when it was soooo bad a few years ago.

@Greta  The 'do-not-call list doesn't apply to business numbers.  And I don't think it works very well anyway - whack a mole situation at best.
